While the show has covered crimes from all across the country, some episodes stand out for truly shocking tales that keep fans looking over their shoulders. This list of the scariest episodes of Forensic Files may have you sleeping with the lights on—or maybe just binge-watching on Netflix.

"A Voice From Beyond" (Season 5, Episode 4)

Imagine finding a body in a barrel... that had been put there 30 years earlier. That's exactly what happened in "A Voice From Beyond." The victim, Reyna Angelica Marroquin, was murdered in 1969. She was pregnant at the time of her death.

In 1999, a man sold his Long Island home and, in the process of clearing it out, found a barrel in a crawl space. He called the police when he discovered a body inside the barrel. Police identified the victim from an address book she was buried with; though the ink had mostly faded, detectives were able to use infrared light to find an alien card number (Marroquin was an immigrant) and the phone number of one of Marroquin's friends.

Eventually, detectives were led to Marroquin's former boss, Howard B. Elkins, with whom Marroquin was having an affair before her death. After police questioned Elkins about the body, he killed himself before being charged with her murder.

"Treading Not So Lightly" (Season 6, Episode 29)

"Treading Not So Lightly" details the story of a girl, Vicky Lyons, who was run over by a truck in 1980—and lived through it, though her near-killer was never identified. The little girl's mother, Crystal Lyons, became obsessed with finding the driver who ran over her daughter. Despite working with detectives and doing her own amateur forensic work, Crystal was never able to find the culprit. Vicky passed away at 34.

"Shell Game" (Season 11, Episode 25)

"Shell Game" showed the viewers what small-town criminals would do for $2,500. Danny Vine and Della Thornton were murdered by three brothers from Tennessee. Vine dealt in mussels, and he and his fiancée were murdered for a truckload of them—a valuable source of mother-of-pearl. One of the brothers was a mussel diver, explaining how he knew Vine. The three brothers were sentenced to life in prison without the possibility of parole for the murders of Vine, Thornton, and their Rottweiler puppy.

"Bio-Attack" (Season 7, Episode 8)

After 751 people got food poisoning in Oregon, authorities discovered that bioterrorists had contaminated 10 salad bars with salmonella, and those bioterrorists were part of a cult. The Rajneeshees, as they were called, tried to make people so ill they couldn't go out to vote, thus ensuring their chosen candidate would win and advance their cult's political platform.
